[ltp] Problem ejecting cdrom drive! T520

[linux-thinkpad@linux-thinkpad.org]

Today I got to the point where I couldn't open my cdrom drive. Here's the
output from eject -v:

eject: using default device `cdrom'
eject: device name is `cdrom'
eject: expanded name is `/dev/cdrom'
eject: `/dev/cdrom' is a link to `/dev/sr0'
eject: `/dev/sr0' is not mounted
eject: `/dev/sr0' is not a mount point
eject: `/dev/sr0' is not a multipartition device
eject: trying to eject `/dev/sr0' using CD-ROM eject command
eject: CD-ROM eject command failed
eject: trying to eject `/dev/sr0' using SCSI commands
eject: SCSI eject failed
eject: trying to eject `/dev/sr0' using floppy eject command
eject: floppy eject command failed
eject: trying to eject `/dev/sr0' using tape offline command
eject: tape offline command failed

I have a fairly new Lenovo Thinkpad T50, Debian with 3.0.0-1-amd64 kernel
using i3wm.

I had been seeing some problem with programs not being able to eject, and
I have had to resort to using "eject", but as you can see that is not
working now. When it was working there were no signs of trouble- odd
noises or such.

Can someone tell me what's going on here? AFAIK I haven't changed anythin=
g
recently that might cause this. I'm unfamiliar with how drives work so
don't know where to start looking.

Thanks,
